ABSTRACT:
A process for preparing polyarylene sulfides which comprises providing at least one cyclic arylene sulfide oligomer of the formula ##STR1## wherein S represents a sulfur atom, groups Ar, which may be the same or different, represent each an arylene radical having 6-24 carbon atoms, groups R, which may be the same or different, represent each a C.sub.1 -C.sub.12 alkyl radical, or a C.sub.1 -C.sub.12 alkoxy radical, or a primary or secondary amino group, n is an integer of from 2 to 50, and m is an integer of from 0 to 15, and heating said cyclic oligomer I in the presence of a ring opening polymerization catalyst so as to form polyarylene sulfide. The process produces polyarylene sulfides improved in chemical, physical and mechanical properties.
